PORTABLE FURNACE FOR HEATING PAVERS SMOOTHING-IRONS.

SPECIFICATION forming part of Letters Patent No. 650,645, dated May 29, 1900. Application filed July 5, 1899. Serial No. 722,793. (No model.)

To (LZZ whom it may concern.-

Be it known that I, ARTHUR W. LINDSAY, a citizen of the United States, residing at Detroit, county of lVayne, State of Michigan, have invented a certain new and useful Improvenient in Portable Furnaces for Heating Pavers Smoothing-Irons; and I declare the following to be a full, clear, and exact description of the invention, such as will enable 0th to ers skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to portable furnaces for heating the irons used to smooth the surface of asphalt paving, and has for its object an improved portable furnace adapted to readily heat the pavers smoothing-iron commonly used in leveling and smoothing off the surface of asphalt paving.

In the drawings, Figure 1 shows the portable furnace in side elevation. Fig. 2 is a plan view of the portable furnace. Fig. 3 is a sectional elevation of the burner. Fig. 4 is a perspective of the air-mixeremployed as part of the burner. Fig. 5 is a rear elevation, at part being broken away.

The burners are several in number, and each consists of a covered or muflied burner 0 mounted on a frame and provided with a common hydrocarbon-tank.

A indicates the framework of the truck, mounted on wheels B B.

0 indicates the casing or sheathing of one of the burners.

D indicates the main storage-tank for gasolene or other suitable hydrocarbon. This tank D is mounted at any suitable place on the framework, either above the burners or on a level with them. The hydrocarbon is forced from the tank D by air-pressure that is generated in any suitable compressor and carried through the flexible tube (Z into the tank D. From the tank D there is an exit-pipe d that leads to the several burners. The several burners are alike in construction, each one consisting of a coil of tubing 0, that is connected by couplings to the pipe (1 that leads from the tank D. The coil 0 has several turns, and below the bottom turn the pipe 0' is bent downward and inward and leads into an air-mixer e, where it terminates with a minute opening. Between the main pipe (1 and the coil 0 is a controlling-valve 6 The coil 0 is inclosed by a protecting-jacket 0 that rises from the fioora of the frame A, and the pipe 0 drops through the deck or floor aand leads into a mixer e, which is partly above and partly below the floor at. There is an inlet-opening 6 into the mixer e below the floor a, and the hanging parts just described are protected from drafts and improper access of air by a casing 0 that hangs from the floor a. Provision is made for the access of air to the mixer by openings 0 that lead into the hanging casing 0 At the top of the casing c is a second deck a, that sup ports the upper end of the several casings c and is provided at each casing with an-opening that corresponds with the casing in size 7c and shape. Above the deck (If, over each burner, is a hood or muffle a, slightly larger than the opening it covers, so that there is around the opening above the burner inside the muflle a a ledge or shelf Z) on which the 7 5 smoothing-iron is sustained. Around the frame of the wagon is a rail 1', arranged to support the long handles of the smoothingirons.

What I claim is--- 8o 1. In a portable furnace forheating pavers smoothing-irons, a chamber-casing O, a supply-pipe coiled around the chamber inclosed by said casing and extending to an air-mixer e, at the lower end of said casing, said mixer being adapted to deliver the mixture to said chamber, means for forcing the hydrocarbon through said supply-pipe, a mufiie at the upper end of said casing and a rest under the muffle for the smoothing-iron, substantially as described.

2. In a furnace for heating pavers smoothing-irons, a plurality of chambercasings mounted upon a truck, a supply-pipe for liquid hydrocarbon passing through each .of 5 said chambers and leading to an air-mixer 1o- In testimony whereof I sign this specification in the presence of two witnesses.

ARTHUR W. LINDSAY.
